Abstract
An in-vehicle control device carries out fuel cut-off for stopping fuel injection from a fuel injection valve when a prescribed fuel cut-off condition including that a lockup clutch with which a torque converter is equipped is engaged and that an accelerator is off is fulfilled. Besides, the in-vehicle control device performs a fuel cut-off suspension process for carrying out fuel injection from the fuel injection valve and releasing the lockup clutch when there is a request to suspend fuel cut-off with the accelerator off. Also, the in-vehicle control device performs a speed increase process for performing shift control of an automatic transmission such that the rotational speed of a turbine impeller with which the torque converter is equipped becomes higher while the fuel cut-off suspension process is performed than when fuel cut-off is carried out.
